"Parallels recently made a definitive statement saying that the company won't be making it easy for users to run OS X in a virtual environment anytime soon. The reasoning behind this was because they don't want to put their users at risk of breaking the OS X EULA - unlike Windows Vista, there is no version of OS X that can be run under a virtual machine - and more importantly, they don't want to strain their (currently good) relationship with Apple. As a followup to that statement from Parallels, I was able to also get in touch with Srinivas Krishnamurti, VMWare's Director of Product Management and Market Development in order to get VMWare's official position on the matter. "Apple does not currently allow running Mac OS X in a virtual machine," he said. "Apple is an important partner and VMware respects Apple's intellectual property."
